Abstract: REINFORCED PLASTIC MOLD FOR CONCRETE PANELS           ABSTRACT OF THE DISCLOSURE A mold especially adapted for forming precast, waffle-shaped concrete panels employs a one-piece mold body of plastic sheet material to provide a reusable mold structure that may be rapidly stripped and reset.  Each corner of the mold body is open; thus, the sides of the mold present pliable flaps due to the inherent flexi-bility of the sheet material and are swung out-wardly after molding is completed in order to release the molded product.  External reinforcing members on the sides maintain the same rigid and true during the molding process.  The corners are held closed by simple locking devices which are readily released for stripping.  Raised portions in the mold body form the characteristic voids in the molded waffle product, and are reinforced and rigidified by a foam filler.  Other features include longitudinally extending expansion joints between the mold body and reinforcing members, holdups on the pliable sides of the precasting mold, and the provision of built-in rebar supports which also form notches in the webs of the molded waffle prod-uct that serve as electrical and plumbing raceways.

Title: Mulching lawn mower
Inventor: SZYMANIS EDWARD
IPC: A01D34/00
Filed: 1978-08-31
Granted: 1981-04-14
Abstract: Case 2651 ABSTRACT OF THE DISCLOSURE     A chuteless rotary scything mulching lawn mower is described which is particularly adapted to be powered by an electric motor including sealed motors.          The cutting chamber includes a toroidal portion bounded by concentric skirt walls wherein the cross sectional area of the toroid increases towards the inner skirt.          The inner skirt slopes downwardly towards the axis of the cutting blade, and terminates close thereto so as to reduce air leakage from the toroid.  Air passage openings are provided into the housing on the axial side of the inner skirt through which cooling air is drawn for the motor.  This air stream combines with air from the toroidal chamber which is redirected by the inner skirt wall to distribute grass cuttings over a comminuting portion of the blade.  The blade is sharpened to a chisel edge along the upper surface thereof, the bevelled surface of the chisel edge functioning as an air propelling surface.  The efficiency of the housing permits blades with less twist to be employed, reducing the incidence of blade cracking.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and treating agent for increasing the yield of deep mined coal mined from a site 100 feet or more below the surface where the particles in the coal are concentrated by froth flotation.  This method consists of utilizing as a promoter or frothing aid about 0.05 - 1.5 lbs of sodium polyacrylate latex per ton of dry coal (0.017 - 0.5 lb of dry sodium polyacrylate per ton of dry coal), having an average molecular weight of about 100,000 to 1,000,000 and more, with a preferred range of 1,000,000 or more.  The preferred promoter or frothing aid for deep mined coal is a water-in-oil latex of sodium polyacrylate preferably used with an alcohol-type frother.  The latex may be utilized neat and self inverts with the assistance of an oil-in-water surfactant (or activator) and the water in the system upon application to form an oil-in water emulsion, or it may be used as a two-part system with an activator (aqueous) to promote in-version.  The latex emulsion has demonstrated superiority as a flotation promoter for deep mined coal over the dry polymer and exhibits synergism over the dry polymer and over the components of the latex emulsion includ-ing a paraffin solvent, a hydrophobic emulsifier such as sorbitan mono-oleate, a solvent such as Espesol 3-E (Charter; an aromatic blend) and stabllizers such as polyisobutylene and aluminum tristearate.

Abstract: ABSTRACT            Splines which are partially inserted into longitudinal grooves in wood members, such as, outdoor light poles, are dis-closed. Conduit (e.g., electrical wires or piping) is recessed in the groove and is protected by the spline. The spline is attached to the member on only one side of the groove so that it moves with that side of the groove as the groove expands and contracts. The outer face of the spline is wider than the mouth of the groove and lies flush against the periphery of the member. Thus, even when the groove expands, the spline's outer face covers the groove and protects the wires.

Abstract: Abstract of the Disclosure Apparatus for moving lightweight articles, for instance thermoplastics cups, in which the articles are moved from one location by ejector pins which push the articles onto a conveyor for transfer to another location. The articles are held in a desired orientation as they are moved by the pins. Ideally, a passage extends through each pin to hold the articles thereto by vacuum which alternates with air pressure in the passage to force articles from the pin onto the con-veyor when the pin is closest to the conveyor. The pins move along guide passages which assist in maintaining articles properly oriented and stabilizing plates are preferred adjacent the conveyor to stabilize articles during transfer onto the conveyor. The apparatus is useful in removing thermoformed cups from sheet and for this purpose a cutting device may cooperate with each ejector pin cutting and then transferring cups.

Abstract: ABSTRACT There is disclosed herein a programmable cardiac pacemaker pulse generator utilizing digital circuitry for controlling the provision of card-iac stimulating pulses.  The pulse generator is capable of having the rate, the pulse width, the pulse amplitude, the refractory period, the sensitivity and the mode of operation programmed.  In addition, the pulse generator can have the output inhibited and can respond to programming signals causing a threshold margin test to be performed, effects of closure of the read switch overridden, a hysteresis function added and a high rate exceeding the normal upper rate limit programmed.  Many of the programmable functions of the pulse generator can either be programmed on a permanent or a temporary basis.  The pulse generator further includes means for signaling the acceptance of a programming signal, and means to reset the program acceptance circuit if ex-traneous signals are detected as programming signals.  The program signal acceptance circuit performs several different checks on the detected pro-gramming signal including a parity check, an access code check and determin-ing if the proper number of signals were transmitted within a given time. The timing circuit of the pulse generator includes a crystal clock oscillator and counter means for counting the clock pulses therefrom to determine the rate of the pacemaker.  The pulse width of each pacemaker pulse is determined by using a voltage controlled oscillator in place of the crystal oscillator to obtain energy compensation due to the battery voltage decreasing with time.
